Don't forget that the court knocking out the punitive provisions of the Medicaid expansion really knocks a hole in the legislation, what the Administration is left with is a law which taxes people who do not purchase medical insurance, but in which many states may well decide not to provide expanded Medicaid coverage, that is the better part of 17 million people who are really doing to take it right in the nose.
The number one target of the GOP was the mandate which has survived. With the mandate it will be possible to insure that the sick as well as the healthy are covered and therefore make the plan economic. The plan can survive without the other measure although it will take some work but it could not have survived without the mandate.
